According to a CBS News report, concerns are also mounting that gonorrhea could soon become resistant to all current antibiotics, officials from the U.S. Centers for Disease Control said.
The CDC report shows nearly 2.3 million cases of chlamydia, gonorrhea, and syphilis were diagnosed in the U.S.in 2017. Some experts believe it may be caused by less-frequent condom use, better diagnostics, and even dating apps.
To put it bluntly, as Jonathan Mermin, director of the CDC's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, did in a CDC press release: "We are sliding backward". This represents the fourth consecutive year of a "steep, sustained" increase in STD cases - a 31 percent increase of 2013 levels. And it manifests itself in many ways, including this public health crisis.
Primary and secondary syphilis diagnoses increased 76 percent (from 17,375 to 30,644 cases).
Chlamydia remained the most common STD reported, with more than 1.7 million cases in 2015.
The CDC is urging doctors to stem the spread of STDs by promoting frank discussion of the infections, testing patients for STDs and promptly treating any cases they find.
Gonorrhea diagnoses almost doubled among gay men - going from 169,130 cases in 2013 to 322,169 previous year. Almost 70 percent of syphilis cases were in gay, bisexual, or other men who have sex with men, the report said. This figure was boosted by a 45 percent increase among 15-24-year-old females.
All three of the diseases are treatable but woman could suffer from permanent damage to the reproductive system and men to the prostate if not addressed.
Chlamydia, gonorrhea, and syphilis are curable with antibiotics.
Emerging resistance to ceftriaxone has not been seen since the dual therapy approach was implemented, and there has not yet been a confirmed treatment failure in the United States when using this recommended therapy.
